Plz help me I don't know how to do this!!!!
m_a_m_a [10]

Answer:

x = 25

Step-by-step explanation:

Since it is an equilateral triangle it means that all the sides are 50. Each side is equal so, if you divide 150 by 3 you get 50. (and since perimeter is the adding of each side)

Now you want to try to figure out what the altitude is of the triangle so you divide it in half. Making the bottom side length now 25 because half of 50 is 25. You now have to use Pythagoreans theorem to figure out the altitude:

c^2 - a^2 = b^2

50^2 - 25^2 = b^2

2500 - 625 = b^2

1875 = b^2

√1875 = b

43.30127019

now you put that into the expression: x√3:

x√3 = 43.30127019

x = (43.30127019) ÷ (√3)

x = 25

Hope this helped!

Total of 6 pies. Two lemon meringue pies cost $3 less than four blueberry pies. Three lemon meringue pies cost #9 more than thre
ioda

Answer:

L Pie - $7.50

B Pie - $4.50

Step-by-step explanation:

Let's create equations with the given things:

1.  Two lemon meringue pies cost $3 less than four blueberry pies.

2L - $3 = 4B

2. Three lemon meringue pies cost #9 more than three blueberry pies.

3L = $9+3B

3. Let's solve these 2 equations

1. -3(-4B+2L=-3)

2. 2(-3B+3L=9)

3. Adding these 2 equations:  

12B-6L = 9 ----(1)

-6B+6L= 18 ----(2)

(1) + (2) => 6B=27

B=$4.50

4. 2L = 4(4.50) - 3

L= $7.50

----------------
